Can't Change Gamma?

[Jundlyfe]

Then good old fallback is to edit the settings.cfg file. For overture this is located in Library/Preferences/Frictional Games/Penumbra/Overture in you home directory.

The gamma configuration option is in that xml file. You can also just delete that file to have the game re-ask the gamma setup question. And this won't lose your saved games.

Thanks; but unfortunately, it wasn't much help.

I looked in Lib/Preferences, and there is no Frictional Games folder. To double check, I deleted the game from apps and re-installed, ran it, quit, and checked again. There's no Frictional Games folder. I also did a spotlight search in the preferences folder, but found no results for "Frictional".

I'm running the game from the Humble Indie Bundle, in case that helps. I tried running the latest patch but had to uninstall, because it asks for a serial, which doesn't come with the bundle (which is supposed to be DRM and serial free...).

I'm having a blast with the other games, so I can't complain, but I really wish I could get this working right.
